Fast Forward and Rocker Gestures

I know it's still early in development, but since Fast Forward was mentioned as a feature in the latest Tech Preview, I might as well point out some issues I've been having. Fast Forward seems unreliable. It works on some sites, but not others (or at least not the same as in Opera 12). For example: [url]http://slickdeals.net/forums/forumdisplay.php?f=9[/url] In Opera 12, Fast Forward takes me to the next page of topics. In Vivaldi, the Fast Forward button is available, but clicking it does nothing. As for Rocker Gestures, Right-click then left-click generally seems to work for Back. However, left-click+right-click doesn't is a little more unreliable. Sometimes it goes forward, sometimes it goes back, and it doesn't seem to implement Fast Forward.
